System and Security​ OS Upgrade: Yocto Krogoth --> Kirkstone, Linux 4.1.15 --> 5.15.71 Enhanced Encryption: TLS 1.3 support via OpenSSL 3.x Webshell Access: Introduced a browser-based command line interface for advanced diagnostics and control. Webshell is not accessible via RA due to lack of WebSockets proxying. Platform Extensibility​ Docker Integration: Replaces the legacy Gen3 “AcquiSuite Module” system with flexible, container-based architecture. Expanded Access: Containers can interact with device data, Modbus TCP/RTU, raw RS485, and the Docker API. Developer-Friendly: Supports multiple programming languages including Go, C/C++, NodeJS, and Python. Logging & Performance​ Solar-Aware Logging: Intelligent retry limits prevent delays when large numbers of devices (e.g., solar inverters) are offline. Performance Visualization: Overview page now includes daily, weekly, and monthly graphs for streamlined data analysis. Security Enhancements​ Dynamic IP Access: “Your IP Address” mode automatically tracks WebUI access IP for secure SSH and container permissions. Custom Rule Support: Define port ranges and catch-all rules to tailor firewall behavior for containerized environments. Documentation Updates​ Devlist API Device Readings API XML Uploader
